Customised
solutions for large diameter logs
Log yard for highest qality requirements
Task
At the Regen site, the existing log yard was to be replaced with a high‑performance, future‑proof solution. Two central requirements were at the forefront: the processing of large‑diameter logs with extreme dimensions, and the particularly gentle handling of the valuable raw material.
Almost 100% of the logs processed require butt reduction – while simultaneously meeting the highest standards of surface quality and material preservation. Every process step, from infeed and singling to debarking, had to be designed to minimise damage and avoid any loss in value.
At the same time, a high level of process automation was required to combine efficiency, transparency and user‑friendliness. The goal was a solution that unites quality, cost‑effectiveness and modern plant logistics – implemented with minimal disruption to ongoing operations
Solution
Together with Holz Schiller, HOLTEC developed a customised plant concept that combines precision, gentle material handling and efficiency. Project manager Daniel Engel coordinated all phases from design to commissioning, ensuring consistently detail-focused implementation.
The logs are unloaded onto a heavy-duty log deck and gently separated via a step feeder. An integrated butt reducer in the tapered‑roller conveyor ensures precise reduction with optimal visibility for the operator. A metal detector reliably identifies any foreign objects and diverts affected logs before they are transferred via a measuring chain conveyor.
At the heart of the installation are six newly developed buffer decks, combining intermediate storage, pre‑sorting and sawmill feeding in a single system. The ejector simultaneously functions as a distributor – a space‑saving and economical solution with high overall performance. As a result, the entire log yard can be operated by just one person.
Implementation took place in two construction stages with minimal interruption to production. After commissioning the new feeding systems, the connection to the sawmill infeed was established during the plant shutdown period, and the complete system was subsequently launched.
The result is an optimised log logistics system with increased buffer capacity, smoother material flow and reduced use of industrial trucks – delivering noticeably higher efficiency and maximum material protection.
